Conservation on Castle Farm

March 02, 2023 2 min read


The Alexander family have been farming in the Darent Valley since 1892. Practical conservation has always been an integral part of day-to-day activities – taking pride in caring for the environment as well as growing crops.


  • Wide grass margins are maintained around fields to provide habitats for wildlife and increase biodiversity.
  • Native flowers are nurtured to provide pollen and nectar for bees, butterflies and insects.
  • Over 30km of hedges, tree-lines and woodland shaws are managed to enhance the landscape and provide corridors for wildlife across the farm.
  • Tree and hedge planting projects are undertaken annually.
  • Hedges are cut to an A-shape to provide dense cover for nesting birds.
  • Over the winter, bare fields are sown with green ‘cover crops’ to improve the soil by preventing erosion, retaining nutrients and sequestering carbon.
  • Cattle manure and lavender compost are spread on the land to increase organic matter and fertility, thereby reducing the use of artificial chemicals and fertilisers.
  • Specialist Owl Boxes have been installed across the farm to encourage owl nesting. 
  • Bee hives are situated in our fields and we partake in regular insect surveys to encourage healthy insect population across the farm. 
  • The farm devotes over 10% of its cropping area to be managed with wildlife and the environment having priority over food production.
  • We are facilitating a river enhancement program; nurturing river biodiversity, supporting healthy fish life and encouraging the presence of water birds.
